INCANDESCENT BURNER.

SPECIFICATION forming part of Letters Patent No. 769,533, dated September 6, 1904. Application iled February 20, 1904. Serial No. 194,565. (No model.)

To 1!, who! it Ill/Lj/ (saucer/t:

Be it known that I, HARRY BARRIXGER Cox, a citizen of the United States, residing at Indianapolis, county o't'Marion, State of Indiana, 5 have invented certain new and useful Improvements in Incandescent Burners; and I do hereby (.leclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it ap- Io pertains to make and use the same.

This invention relates to certain improvements in illuminating gas or vapor burners, and more particularly relates to improvements in gas or vapor burners of the incandescent-mantle type.

It is an object of my invention to increase the candle-power or etliciency of incandescent-mantle or \Velsbach burners by directing or deflecting the burning mixture radially or laterally against or adjacent to the surrounding or annular wall of the mantle and by so breaking up and spreading or deflecting the burning mixture within the mantle by improved means as to locate the points of most intense heat or combustion adjacent to such portions of the mantle as will produce a very high etliciency of illuminating power, a thorough mixture and commingling of the ingredients of the combustible mixture to produce more perfect combustion, and to cause a radial diffusion of more intense light-rays from the mantle.

'ith these and other objects in View my invention consists in certain novel features in construction or in combination or arrangements of parts, as more fully explained hereinafter.

Referring to the accompanying drawings, which show for purposes of explanation vari- O ous forms from among others merely as examples of means which can be employed in carrying my invention into eli'ect, Figure 1 is a perspective view of a portion of an ordinary incandescentnnantle orlVelsbach burner, showing my invention applied thereto, parts being broken away or shown in section. Figs.

2, 3, 4, and 5 are detached views showing various forms in which my invention can be embodied.

In the drawings, a is an ordinary or suitable 5 \Velsbach or incandescent-mantle burner,having the top gauze diaphragm or cap 7), through which the combustible mixture of air and gas or vapor is delivered into the combustion space or chamber within and formed by the incandescent mantle or hood 0, which can be of any suitable or ordinary construction or, formation. Any suitable or ordinary means can be provided to suspend or support the mantle in the usual vertical position with its lower open end receiving the gauze cap .71. The mantle is usually suspended by the loop,

cord, or connections I! of non-combustible material extending across the open upper end of the approximately cylindrical mantle. In Figs. 2, 3, and 5 I show mantle-supporting yokes or standards. In Fig. 3 I show the ordinary mantle-supporting post or standard K, from the hooked lateral end of which the mantle is suspended. In Fig. 5 I show the ordi- 7o nary U-shaped or yoke form of mantle-supporting rod 2, having the central top depressed portion or deflection which forms the seat in which the mantle-suspending loop rests.

\Vithin the vertically-clongated combustion space or chamber inclosed by the mantle I arrange one or more bodies to spread, break up, and deflect the combustible mixture. For instance, in Fig. 1 I show a central vertical rod g, at its lower end seated in the vertical central 8o socket l2. in the gauze cap and held in a perpendicular position thcrcby. This rod extends centrally and longitudinally throughout the length of the mantle and is shown forming the mantle-support, although the broad features 5 of my invention are not so limited. I show the upper end of this rod or post formed with a transverse seat or notch which receives the suspending-loop (Z of the mantle. On this rod I arrange one or more disks X. In 9 Fig. 3 I show one disk '1', located on the rod 0 about midway the length thereof. In Fig. 2

, versely within the mantle to between its periphery I show two disks i, and in Fig. 1 three disks 2', distributed along the rod 9. The disks are shown circular in form and horizontally and concentrically arranged on the rod and within the mantle and transversely spanning or partially spanning the combustion-chamber inclosed by the mantle. In Fig. 1 the disks are shown about equally spaced, and the disks of the series are of different diametcrs that is, the lower disk is of comparatively small diameter, the next disk above of greater diameter, and the top disk of the greatest diameter, leaving a comparatively narrow space and the inner surface of the mantle. The disks are formed of any suitable material to form deflectors or spreaders to break up the heat-column Within the mantle and to deflect the combustible mixture radially or laterally toward the mantle and force the burning mixture outwardly from the center line of the combustion-chamber, causing the most intense combustion to take place around the inner surface of the mantle. The transverse interrupting-disks are preferably rigid with the supporting-rod and of the necessary thickness or body and composed of suitable material for the purpose intended.

While an important advantage is attained by throwing the burning mixture toward the surface of the mantle to greatly increase the incandescent intensity of the mantle, yet the essence of my invention resides in the economy in gas effected by attaining perfect mixture and commingling of the ingredients of the combustible mixture'and perfect combustion by the employment of means arranged transpositively and abruptly interrupt the upward flow of the combustible mixture and cause thorough commingling of the air and vapor or gas and perfect combustion. The disks abruptly and positively interrupt this upward flow of the combustible mixture and cause what might be termed cross-currents or eddies, which accomplish the desired results, and which cannot be accomplished by a mere flamespreader arranged closely adjacent to the gauze or at the extreme lower end of the mantle.

It is essential if but one positive transverse interrupter or disk be employed that the same be located about at the center of the length of the mantle to positively arrest and break up the ascending combustible mixture and to cause the cross-currents at the center of the length of the mantle. However, I prefer to employ a series of positive transversely-arranged interrupting faces or surfaces of increasing diameter toward the upper end of the mantle, as results are thereby attained which are not possible where the smooth tapered merely deflecting surface is employed longitudinally of the mantle and which are not possible where only the single disk is employed even if located at the center of the length of the mantle.

'I/Vhile I prefer to employ the series of transverse disks which form the intermediate transverse commingling and combustion spaces between the parallel faces of the disks, yet other forms of interrupting devices having the transverse abrupt faces can be employed. For instance, in Fig. t I show the same in the form of a single elongated body or core 7', gradually tapering or reducing downwardly in size and formed with the annular downwardly-facing deflecting-shoulders 1'. If desired, the circumferential edges of the deflecting-disks 0? other bodies can be beveled inwardly and downwardly, as shown at k in Figs. 2 and 5, to increase the spreading or deflecting action.

In Fig. 5 I show the disk-carrying rod or support suspended and supported from its upper end by having its upper end rigidly secured to the top portion of the mantle-supporting yoke. mantle, and internal deflecting-body can thus be placed on the market and simultaneously applied to the burner.

It is evident that various changes and modiconstructions, and arrangements of the parts described without departing from the spirit and scope of my invention. Hence I do not wish, as at present advised, to limit myself to the exact constructions shown.

What I claim is- 1. An incandescent-mantle burner having a reticulated diaphragm at the lower end of the combustion-chamber inclosed by the incandescent mantle, a mantle-support, and interrupting means presenting a horizontal face arranged transversely of the chamber inclosed by the mantle and about midway between said diaphragm and the upper end of the mantle to abruptly and positively arrest the upward flow of the combustible mixture and forming a commingling-chamber below said face, said means being concentrically arranged within and out of contact with said mantle.

2. An incandescent-mantle burner having a vertical series of spaced transversely-arranged interrupting-faces arranged within and out of contact with the mantle to abruptly and positively interrupt the upward flow of the combustible mixture, said faces forming commingling-chambers below the same.

3. An incandescent -mantle burner having a vertical series of spaced horizontal disks arranged within the mantle and forming transverse interrupting-faces to positively and abruptly interrupt the upward flow of the combustible mixture, said disks forming commingling-chambers below the same.
